Synthesis of TiO2 nanodendrite for dye-sensitized solar cell application

TiO₂ nanodendrite (ND) arrays have been synthesized on FTO substrates using a wet-chemical route. The aligned TiO₂ nanowire (NW) array was first synthesized on the FTO substrate by hydrothermal method. The branches of the TiO₂ NDs were then formed using an aqueous chemical bath deposition (CBD) without any capping agent followed by another hydrothermal process. With an anode thickness of ~3 μm, TiO₂ ND dye-sensitized solar cell (DSSC) has superior photovoltaic properties to TiO₂ NW cell.
